Hi,

I am currently trying to run the Ostrosoft Winsock Component on Windows Server 2008 R2 Foundation Edition.

I have added the component and it shows up in the toolbox as the object and in my project I have the following references:

AxInterop.MSWinsockLib

AxOSWinsockControl

Interop.MSWinsockLib

Interop.OSWinsckControl

OSWinsckControl

I'm wondering if this version of Windows 2008 is supported?, as when I try to run I get the following error:

An error occurred creating the form. See exception.InnerException for details. The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

******* SOLVED ***********

I was trying to run it using a 64-bit operating system and the vb.net application didn't like it, to solve it did the following:

Go to your vb.net project directory and locate the file : <PROJECT NAME>.vbproj and open with notepad.

Locate the following lines:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
    <DebugSymbols>true</DebugSymbols>
    <DebugType>full</DebugType>
    <DefineDebug>true</DefineDebug>
    <DefineTrace>true</DefineTrace>
    <OutputPath>bin\Debug\</OutputPath>
    <DocumentationFile>WRX Crane Comms.xml</DocumentationFile>
    <NoWarn>42016,41999,42017,42018,42019,42032,42036,4202 0,42021,42022</NoWarn>
  </PropertyGroup>
  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">
    <DebugType>pdbonly</DebugType>
    <DefineDebug>false</DefineDebug>
    <DefineTrace>true</DefineTrace>
    <Optimize>true</Optimize>
    <OutputPath>bin\Release\</OutputPath>
    <DocumentationFile>WRX Crane Comms.xml</DocumentationFile>
    <NoWarn>42016,41999,42017,42018,42019,42032,42036,4202 0,42021,42022</NoWarn>
  </PropertyGroup>

Add the following line before </PropertyGroup> on both instances: <PlatformTarget>x86</PlatformTarget> and it should then look like below:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
    <DebugSymbols>true</DebugSymbols>
    <DebugType>full</DebugType>
    <DefineDebug>true</DefineDebug>
    <DefineTrace>true</DefineTrace>
    <OutputPath>bin\Debug\</OutputPath>
    <DocumentationFile>WRX Crane Comms.xml</DocumentationFile>
    <NoWarn>42016,41999,42017,42018,42019,42032,42036,4202 0,42021,42022</NoWarn>
    <PlatformTarget>x86</PlatformTarget>
  </PropertyGroup>
  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|AnyCPU' ">
    <DebugType>pdbonly</DebugType>
    <DefineDebug>false</DefineDebug>
    <DefineTrace>true</DefineTrace>
    <Optimize>true</Optimize>
    <OutputPath>bin\Release\</OutputPath>
    <DocumentationFile>WRX Crane Comms.xml</DocumentationFile>
    <NoWarn>42016,41999,42017,42018,42019,42032,42036,4202 0,42021,42022</NoWarn>
    <PlatformTarget>x86</PlatformTarget>
  </PropertyGroup>

Save and re-run the application...it should now work.
